When I tried to renew my free license, I got this response within avast on my machine, "You have exceeded maximum number of attempts. Please try again later." I haven't made any attempts before this one. I pressed a button early on, and according to my account when I logged directly into Avast.com it says I'm renewed until next year. So it's really not a problem, but I wondered if someone had tried to use a password cracker and exceeded the number of attempts. No one has access to my machine other than me.
